Calculates the absolute load impedance, reflection coefficient, VSWR, return loss and mismatch loss of a load. Enter the source characteristic impedance and the load impedance then press "Calculate" below. INPUT DATA Source Impedance: Ohms Load Impedance R: Ohms Load Impedance J: Ohms RESULTS Absolute Load Impedance: Ohms Load Reflection Coefficient: Load VSWR: Load Return Loss: dB Load Mismatch Attenuation: dB This calculator uses JavaScript and will function in most modern browsers. For more information see About our calculators. The absolute value of the load impedance is calculated from the complex impedance (R + j). Where R is the Real part of the impedance and j is the Imaginary part of the impedance The Load Reflection Coefficient ( Γ ) is calculated using the complex impedance of the load and the characteristic impedance of the source. Where Zo is the Source Impedance The VSWR is then calculated using the Reflection Coefficient The Reflection Coefficient is used again to calculate the Return Loss The Reflection Coefficient is used yet again to calculate the Mismatch Loss Various equations for Voltage Reflection Coefficient and VSWR are also available at:http://www.spectrum-soft.com/news/fall2009/vswr.shtm Calculate VSWR from Forward and Reverse Power Forward Power (W) Reverse Power (W) VSWR Forward Power (dBm) Reverse Power (dBm) VSWR Need Help? click here
